Common causes
Alarms usually point to a high water level, a pump fault or a blower or air fault. Power outages and tripped circuits can also set them off. Your plant's manual explains what each alarm means.
What to do now
- Check the power to the plant, including the safety switch.
- Cut back water use: hold off on washing, run shorter showers.
- Don't open the tank or touch electrical parts.
- Call your AWTS service provider.
If wastewater is overflowing, keep people and pets away and treat it as urgent. More on septic problems.

Common questions
Is an AWTS alarm an emergency?
Not always, but treat it as urgent. It means the system has detected a fault. Cut back water use and call your service provider.
Can I just turn the alarm off?
You may be able to mute the sound, but the fault is still there. Don't switch off power to the plant unless the manual or your technician tells you to.
